Specification of Letters Patent.

Patented Nov. 12, 1912.

Application filed June 8, 1908. Serial No. 437,302.

To all whom it may concern Be it known that I, WILLIAM A. Sons, acitizen of the United States, residing at Minneapolis, in the county ofHennepin and State of Minnesota, have invented a new and usefulPrinting-Press, of which the following is a specification.

. invention relates to improvements in printing presses and moreparticularly to that class employing an ink transferring medium betweenthe type and cotiperating pressure element. A machine of this type isessentially useful for duplicating type written work and can be operatedin business ofiices by inexperienced persons.

Among other advantages in. my invention are simple and inexpensiveconstruction, adjustability of the parts, uniformity of impression bythe type, and greater speed with reduced power and effectivenessin'operatlon than with machines of its class heretofore in use.

In the accompanying drawings forming part of this specification, Figure1, is a plan view of my invention; Fig. 2, is a side vlew;

Fig. 3, is another side View taken in the opposite direction from thatin which Fig. 2 is taken; Fig. 4, is a longitudinal section taken on theline X-X of Fig. 1; Fig. 5, is

a transverse section taken on the line YY of Fig. 1; Fig. 6, is a'detailside view illustrating the inking ribbon feed mechanism; Fig. 7, is alongitudinal section through the center of the impression roller; Fig.8, is a longitudinal side view of the bed and the construction of what Ihave chosen to term the auxiliary guiding mechanism for the impressionelement; and Fig. 9, is a detail View partly-in section of one of theadjustable springs which assists in depressing the pressure or guidebars.

In the drawings A represents a substantially horizontal, rigid bed whichis secured by brackets 2, to longitudinal sides 3 and 4 which form astand. The surface of the bed is finished in a true plane for thetypeform B to rest upon and has a pair of longitudinal ribs 5 whichserve to reinforce the strength of the bed. At the forward and deliveryends of the machine are two transverse shafts 6 and 7 upon which aresecured at enial distances apartsprocket wheels 8, 9, l and ll. pair ofparallel link bolts 12 and 13 travel at the same surface speed. Betweenthese'belts l pon these sprocket wheels a sion roller is thereby causedto impinge against the type 15 in the type form during each cycle of thebelts. The shaft 7 as shown is driven by a transverse shaft 16 and adrive pulley 17 thereon. The transverse shaft 16 is operativelyconnected withthe shaft 7 by means of intermediate worm.

gearing 18, said shaft-and worm gearing being suitably journaled in thecasing 19 whichis secured on the side 3- of the stand by bolts 20. Oneend of theshaft 7 projects through the casing 19 so that a hand crank(not shown) may be attached to the machine for operating it whendesired.

The impression roller C consists of a shell 25 having on its surface athin jacket of resilient material such as vulcanized rubber and throughwhich shell the shaft 14: extends longitudinallyfl The roller is freelyjournaled upon the shaft 14 by means of ball bearings 27 and 28 ofordinaryconstruct-ion which are located intermediate of the ends andwithin the casing of the roller, the bearing places being situated sothat pressure upon'the surface of the roller is equally distributed anda uniform impression always made. I have found in practice thisconstruction of roller particularly effective, for shoulder slight bendoccur in the shaft or a narrow form of type be used the bearings causethe shell to run true while with prior art devices a slight inequalityin the turning of the roller under such circumstances has resulted inproducing a poor quality of work or in the printing press becomingwholly inoperative. In all other machines the line of travel of theimpres-' sion roller is determined by its journal bearings while on thismachine the perimeter of the roller travels over the type conforming toany inequalities thereof. The ends of the shaft 14 arefreely journaledin flanges 29 on a pair of the links of the belts. Immediatelyadjoining" each end of the roller, guide wheels 30 are rigidly-journaledupon the shaft 14. On one end of the shell 25 is a metal wear ring 31and near each end of the jacket 26 is a circular space 32.

Above the roller (when on the upper lap of the belts) is pressure orguiding mecha- 52 in the ends of the spring bars 48.

nism which serves to press the impression roller downwardly toward thetype in the form during each stroke of the impression roller. Thispressure mechanism has apair of longitudinal and parallel pressure orguide bars 35 and 36 below the lower edges of which the guide wheels 30impinge and cause the roller to run over the surface of the type in theform on the bed of the machine. These pressure bars are carried by meansof transverse supports 37 and 38 which are rigidly secured upon brackets39 on the sides of the stand by means of the bolts 40. The ends of thepressure bars rest upon inclined upwardly extending draw shoulders 41which are formed on the upper surfaces of shift bars 42 when thepressure bars are in superior position. The corresponding ends of theshift bars at one side of the machine are notched at 43 and a pair ofcrank arms 44 have their power ends 45 working in said notches and theirwork ends rigidly secured upon a longitudinal shaft 46 which isjournaled in two of the brackets 39. A handle 47 is secured to the shaft46 and by swinging it backward and forward said shaft is turned and theshift bars 42 moved. lVhen the handle 47 is operated the shoulders 41either raise the pressure bars into superior position or allow them torecede. Above'the shift bars 42 are a pair of spring bars 48 the ends ofwhich rest across the ends of the pressure bars. These spring bars aresecured to the transverse supports 37 and 38 by vertical screws 49passing through said spring bars substantially midwaybetween their ends.The ends of the pressure bars are held in place by their shoulders 50,and pins 51 passing freely through shits T e ends of the spring bars 48are held down under spring pressure below deep seated cups 53 in whichare held helical expansion springs 54 through which verticalbolts-extend and pass through the ends of spring bars 48 into thetransverse supports 37 and 38. The downward pressureexerted against theends of the spring bars 48 and in consequence upon the ends of thepressure bars can be varied by adjusting the vertical bolts 22 or 49.Below the end of each pressurebar is a stop 55 which is secured to thetransverse supports 37 and 38 by means of screws 56 passing throughslots 57. These stops have inclined shoulders 58 which limit thedownward movement of the pressure bars by their ends resting thereon. By

loosening the screws 56, moving the stops and setting said screws, theinclined shoulders 58 can be changed in position to limit the downwardmovement of the pressure bars. All of the inclined shoulders on thestops 55 and shift bars 42 taper in the same general direction. As thebelts travel around the bed, the wheels 30 impinge and run upon thelower edges of the pressure bars and cause the roller to press downtoward the type in the form. The wheels 30 thus act as anti-frictiondevices and leave the impression roller to revolve upon its shaftfreely. The wheels 30 on the roller do not come into contact with thelongitudinal support bars 60 in the operation of the machine.

.The auxiliary guiding mechanism, which is primarily for preventing theimpression roller from coming into contact witlrthe form on the bed andthe inking ribbon during the entire movement of the impression rollerwhen the pressure bars are in superior position and for revolving theroller forwardly at the same surface speed as that of the belts when thepressure bars are down, is provided with a pair of longitudinal track orguide bars 65 which are located below each end of the impression rollercasing. Each of these track bars 65 is mounted upon a pair of verticalstud bolts 66 to the lower ends of which are secured lock nuts 67 whichpermit but limit vertical movement of said track bars. Helical springsaround said vertical bolts are interposed between the track bars and thebed, having sufficient expansive strength to cause the roller to rideupon said track bars when the pressure bars are in superior position butare depressed when said pressure bars are down. The ends of the trackbars are rounded off at 68 so that the roller is adapted to run freelyon and off of the same. It is thus evident that the roller shell is re-.volved at. equal surface speed as the advance movement of the belt andis adapted there'- by to make an even impression in cooperation with thetype and other parts when printing and does. not disturb the transferinking medium or the material being printed upon.

Adjoining the auxiliary guiding mechanism are devices which are adaptedto raise the roller in exact alinement to work in a horizontalplane uponthe type without disturbing the latter when the pressure bars are down.These devices have a pair of longitudinal and parallel bars 70 fromwhich stud bolts 71 depend through the bed. Helical expansion springs 73surround the stud bolts 71 and impinge against the lower surface of thebed and lock nuts 72 on the lower ends of said bolts thus tending todraw the bars 70 toward the bed. For the purpose of raising and loweringeachbar 70 a pair of wedge blocks 74 is provided each block being placedwith its inwardly tapering end sliding over the bed and impingingagainst one of the ridges 75, which are near the ends of the bars 70.The wedge blocks 74 are driven below the bar 70 and withdrawn by anadjusting screw in the form of a stud bolt 76 projecting from the bedand. provided with a threaded collar 77 running in a groove 7 8 in thelower surface of the block. Upon the upper edge of each bar 70 is a pairof skids 80 which are adapted to rest in the path of the'roller when thepressure bars are down. These skids are in the form of blocks havinginclined shoulders 81 up and down which the impression roller is adaptedto run and longitudinal slots 82 through which set screws 85 pass intothe bar 70 and hold the skids longitudinally adjusted .thereon. Thesprings 73 on the stud bolts 71 referred to permit the skid bar 7 0 tobe raised by the wedges 74. The skids raise the impression guides forcausing the impression roller or element to cooperate with the type inthe form; and the resiliently supported guide bars 65 serve to revolvethe impression roller when said bars 35 and 36 are down HIIClftO' guidethe impresion element out of cooperation with the type holdingelementwhen the pressure bars are in superior position.. It will benoted that the lower edges of the pressure bars incline slightly downtoward the inner portion of the machine at 83 so that the impressionroller will be gradually guided with its surface in cooperativealinement with the type in the form.

. Running transversely across the bed and above the type form is aribbon D of suitable transfer material. In practiced have used a ribbonor web of material similar to that employed in typewriting machines anda ribbon of thin paper or parchmenteeated withink thelatter producingbetter results for some classes of work than that which is possible fora transfer web to'produee. This machine being capable of minute adustment of the parts and smooth cooperation between the impression andthe type holding 'elenients causes little Wear upon the ribbon andpermits the use of thin inked parchment While with machines of the classof this invent-ion heretofore used itis necessary to employ a strongweb. This machine being adapted to run the lines of type longitudinallywith the travel of the impression ele ment also permits the'use of atransfer material made of paper or equivalent material.

The ribbon D passes horizontally across and" around longitudinalanti-friction roll-.

ers 90 above the bed ..thence downttlniough slots 91 in the bed, aroundanti-friction rollers 92 below the surface of the bed, to magawith theteeth of the ratchet wheel.

zine spools 93 and 94 upon which the ribbon is adapted to be wound. Theanti-friction rollers 90 and 92 are journaled in the bed.

The spools 93 and 94 are mounted upon longitudinal shafts 95 and 96which are journaled on magazine frames 97. These frames are formed onthe sides 3 and 4 of the stand and are closed byhingeddoors 98 which arelocked by spring snaps 99. The shafts 95 and 96 are of the usualconstruction for supporting magazine spools of the characterdescribedand each is provided on one end with a beveled gear 100. Adjoining theends of the shafts 95 and 96 upon which said beveled gears are mountedis a transverse shaft 101 journaled and free to slide in the sides ofthe stand and upon which are mounted beveled pinio-ns 102. By

moving the shaft forward or backwardfirst one or the other of saidbeveled pinions is adapted to be thrown into mesh Withone of the beveledgears 100 thus causing one of the spools to Wind the ribbon and theother to pay it out or vice versa. By running the ribbon across thelines of ty'pe'instead of with the lines as i' other machines the edgesof the ribbon do I ot curl. A handle 103 on the end of. the shaft 101 isfor the purpose of operating the spools by hand to move the ribbonacross the type holding element. The shaft 101 is turned a step forwardeach time the impression roller passes over the bed of the machine bysaid roller impinging against a dog E as ill11st1' %l. in- FigJG' of thedrawings. The dog E consists of a bell crank lever pivoted at its angleby means of a pin 105 upon one of the track bars 60 near its overhangingend and having one arm 106 curved upwardly in the path of the Wear ring31 on the impression roller. The other arm 107 of the bell crank leveris connected to a. rocker arm 108 by'means of a rod 109, said rockerarm-being rigidly secured .toaro'ck shaft 110 whichis pivoted "in theforward end of the track bars 60.

The rock shaft 110 carriers a lever 111 which is operatively connectedto a ratchet dog carrier 112 by means of a reach rod 113. The ratchetdog carrier is freely mounted upon the shaft 101 adjoining a ratchetwheel 114 which is rigidly secured upon said shaft. A dog 115 is pivotedat 116 upon the carrier 112 and is adapted to engage the teeth of theratchet wheel when the carrier is moved in one direction andto sweepover said teeth when the carrier is reversed. A spring connected by oneend to an arm on the dog and by its other end to an arm on the carriertends to hold the dog in engagement 118 secured to the bed engages theteeth 0% the ratchet wheel and prevents the shaft 101 reversing when thecarrier moves its dog 115 back. It is thus evident that each time theimpression roller moves over the bed and immediately after ithascooperated with the type holding element it impinges against the leverarm 106 and depresses it as shown in Fig. 6 and thereby turns the shaft101 forward and moves the transfer ribbon a step across thet-ype holdingelement thus presenting a fresh transfer surface to the type. A spring119flsecured to the bed and to the arm 109 returns the parts of theribbonfeeding mechanism described into normal position as shown in Fig.4. By changing the lever to one of the pivot openings 129 the feed-maybe varied to a greater or less extent as desired.

A system of paper guides is employed to receive the paper to be printedupon and by its use it is possible to register the paper both quicklyand accurately. Cooperating with this system of paper guides isprovided, means for automatically removing the paper, after it has beenprinted upon, from the machine. The paper guides consist of alongitudinal and vertical plate F which rests normally upon the ribbonabove the type form on the bed and is secured to a bifurcated support125 through which a transverse rod 126 supported on the side of one ofthe pressure bars 35 passes freely. A collar 127 through which the rod126 also passes is secured between the bifurcations of the support 125by means of the set screw 128. By loosening this set screw thelongitudinal guide can'be set in any desired position transversely.Supported upon the rock shaft 110 are a pair of transverse guides 130for the paper. These guides 130 can also be set in any desiredpositiontransversely by means of the set screws 131. The transverse guides 130consist each of a, pair of upper and lower jaws 104 which are securedthrough longitudinal slots 132 to a longitudinal arm 133 by means of ascrew 134. By loosening the screws in the transverse paperuides'thmjawmi said guides can be extent ed to adjust said giii'deslongitudinally. The lower jaw of each trans verse guide carriesa stop135 against which Each time the impression roller cooperates with thetype holding element it impinges against the arm 106 of the ribbon feedmechanism and tilt-s the rock shaft 110 lifting the transverse paperguides intothe position indicated in Fig. 6 and the rearward edge of thesheet of paper which has been previously printed upon. At this point themechanism for removing the paper from the machine cooperates with theguides by engaging the rearward edge of the sheet of paper which hasbeen lifted by the guides and sliding the sheet of paper off the bed.Secured between the link belts by rigid connections with two of theirlinks a transverse shaft 136 and upon which are 65 rigidly secured apair of jaws 137. At

the delivery end of the machine is a carrier brush 138 which is mountedupon a transverse shaft 139.. This shaft is journaled in bearings 140upon the sides 'of chine after it-has been printed upon. The

carrier brush operating at an accelerated speed causes the carriermechanism to work efficiently and effectively to the end desired.Suitable guard plates 145 secured to the sides of the stand protectv themechanism from dust and the operator from danger'by coming into contactwith the working parts. As the belts travel the guide F sweeps over theimpression roller and the carrier shaft 136'. The grooves 32 in theimpression roller" permit the roller to operate out of contact with theribbon guide rollers 90. v

In operation the sheets of paper to be printed upon are placed by handone. at a time against the guides upon the form with their forward edgesprojecting between the jaws 104 of the transverse guides. As the beltsare driven forward the impression roller and carrier upon the belts passfreely above the type holding element and out of contact with the paperto be printed upon. \Vhen the handle 47 is thrown forward and thepressure or guide bars 35 and-36 lowered the impression rollercooperates with the type holding element and causes the type to printupon the sheet of paper in the machine. As the impression rolleradvances from and after it has left the type holding elementit'depresses the dog E and causes the ribbon feed mechanism to move thetransfer material a stepforwar'd across the 110 type 'n element Mgr sameaction lifts the transverse guides into sltion shown 1n Fig. 6 thusraising the rearwar a transverse edge of the paper impinges.

edge of the sheet of paper above the face of the type form. The jaws 137following the impression roller on the belts thereupon, engage theforward edge of the sheet of paper and push said sheet over the carrierplate 143 and onto the carrier brush 138, the latter ejecting the paperquickly from 12 the machine. Thecarriers carry the paper (substantially)without contact with the ribbon.
